It could very well be. If it has limited resever power for you towing
needs now, it will get worse and as I said braking will be reduced a
bit too. The only way you can honestly maintian same pulling power
with bigger tires is a axle ratio change which can be expensive but it
does restore your overall effective drive ratio when using bigger
tires. Some think they can tune this out with a exhaust of air filter
but you cannot as it deals with simple physics and mechanical advange
over the load and more engine torque is require for same ground
tractive effort. ALso remember that this "power loss" will be felt in
all gears including starting a load out on boat ramp so you know where
you are now performance wise and simply understand the towing
performance will degrade with bigger tires. How much of a issue this
is for you again depends on "where" you are at now in the towing
performance curve with your load. Another way to look at this, if you
install bigger tires with stock axle gears, it has the same net effect
as taller axle gears with stock tires or a net loss of effective
pulling power in every gear due to a taller overall effective final
drive ratio.

The problem is when you do not have a lot of room due to something
unexpected happens at the wrong time (like they usually do) and you
need to stop. Something to think about anyway.

This guy is just a insecure Troll so take with a grain of aslt what he
